274 FREQUENCY MODULATION, Volume IThe following characteristics should also be considered in anevaluation of the system:1. Adequate receiver gain ahead of the locked-in oscillator mustbe provided if distortion of the weaker signals (due to theoscillator falling out of step) , is to be prevented.2. When the receiver is tuned through a signal, more noticeabledistortion occurs at the edges of the receiver response characteristicthan is obtained with a corresponding conventionalreceiver.AcknowledgmentThe writer wishes to acknowledge the valuable assistance of Messrs.M. S. Corrington, G. L. Grundmann, W. R. Koch, and W. F. Sandsduring the development of the frequency-dividing locked-in oscillatorfrequency-modulation receiver.
